Morin is a yellow chemical compound that can be isolated from Maclura pomifera (Osage orange), Maclura tinctoria (old fustic), and from leaves of Psidium guajava (common guava).[1] In a preclinical in vitro study, morin was found to be a weak inhibitor of fatty acid synthase with an IC50 of 2.33 μM.[2] Morin was also found to inhibit amyloid formation by islet amyloid polypeptide (or amylin) and disaggregate amyloid fibers.[3]

Morin exhibit inhibitory action against IgE-mediated allergic response. Morin treatment significantly down-regulated expressions of BLT2, NF-κB, and Th2-cytokine (TNF-α, IL-1β, IL-4, IL-6, and IL-13) in lungs of murine model of allergic asthma.[4]

Morin can be used to test for the presence of aluminium or tin in a solution, since it forms characteristically fluorescent coordination complexes with them under UV light.
